I just installed the OEM Ipod connector into my 2006 S. I have a basic radio (no Bose, no sat nav, no sat radio, single disc cd). On some songs there is minor distortion, like the crackling sound of an old record. This happens on songs with higher amounts of treble, but not on bass songs (doesnt happen on rap, r&b, and most dance/electronica). For example it happens alot on Coldplay's A Rush of Blood to the Head album. Anyone experience this problem? The problem doesnt happen at all when I listen to CDs or the radio.
